How easy is it to do temporary or permanent hearing damage with such a device? I'm not speaking for or against this as a safety device, but it's not the sort of thing you'd want to leave where your toddler could reach it. Or your cranky tween. Or your angry spouse who gets tired of listening to you sometimes.
My understanding is the threshold of hearing damage begins around 150db. This device claims 140db. I did not use the decibel measuring device on my phone. It was on for about 5 seconds and I was standing at conversational distance. After it was deactivated, I did not having ringing or pain in my ear. I know that isn’t exactly scientific. I might see this person later today so I will try to ,ensure with the decibel meter if I get the chance.
I also pulled the pin and it takes a bit of little effort, it doesn’t just slip right out. To a toddler, the cord holding the pin would likely just look like wrist band.
